Offset hinge assembly for mobile compute devices

ABSTRACT

A convertible mobile compute device comprises a lid, a base, and a hinge assembly coupled to the lid and the base. The hinge assembly includes a lid hinge bracket secured to the lid and configured to rotate about a lid hinge axis. The hinge assembly also includes a base hinge bracket secured to the base and configured to rotate about a base hinge axis. The lid hinge axis is offset from a centerline axis defined by the lid, and the base hinge axis is offset from a centerline axis defined by the base. As described herein, the offsetting of the hinge axes provides for a smaller a lid-to-base gap when the convertible mobile compute device is positioned in a closed mode relative to when the convertible mobile compute device is positioned in a tablet mode.

BACKGROUND

Mobile compute devices come in a variety of forms, including cell phones, laptops, and tablets. Some mobile compute devices may fit into multiple categories, such as a laptop with a display that can be folded 360 degrees and convert from a clamshell-mode configuration to a tablet-mode configuration. Typically, thinner designs of mobile compute devices are more desirable by consumers. However, designing a mobile compute device to be thinner often incurs an adverse impact on its thermal performance.

Many convertible mobile compute devices, such as laptops configured to convert from a clamshell-mode configuration to a tablet-mode configuration include a lid, in which the display is typically mounted, and a base, in which the keyboard is typically mounted. To ensure proper thermal performance, typical convertible mobile compute devices are designed such that the lid-to-base bush height (i.e., the spacing between the lid and the base) is the same in both laptop and tablet modes. However, such a requirement leads to thicker designs.

Referring now to FIG. 1, an illustrative convertible mobile compute device 100 includes a base 102 and a lid 104 coupled together via a hinge assembly 106. The base 102 illustratively includes a keyboard 110, and the lid 104 illustratively includes a display 112. The keyboard 110 may be embodied as any type of keyboard such as a physical or virtual (e.g., touchscreen) keyboard and includes a number of keys selectable by a user to provide input to the convertible mobile compute device 100. Similarly, the display 112 may be embodied as any type of display capable of displaying information to a user of the convertible mobile compute device 100 such as a light emitting diode (LED) display, a touchscreen display, liquid crystal display (LCD), or other display. Of course, it should be appreciated that in some embodiments, the convertible mobile compute device 100 may not include the keyboard 110. In such embodiments, the display 112 may include a touchscreen, which may be used as a keyboard during operation of the convertible mobile compute device 100.

The hinge assembly 106 couples the base 102 and lid 104 and is configured to allow movement of the lid 104 relative to the base 102 along a lid-to-base axis 108. In use, as discussed in more detail below, the hinge assembly 106 facilitates the positioning of the convertible mobile compute device 100 into one of multiple physical configuration modes, such as a closed mode, a clamshell mode, a tent mode, and a tablet mode. To do so, a user may move the lid 102 along the lid-to-base axis 108 to achieve the desired physical configuration mode of the convertible mobile compute device 100. As such, the convertible mobile compute device 100 may be embodied as any type of computation or computer device positionable into multiple physical configuration modes (e.g., clamshell mode, tent mode, tablet mode, etc.) and capable of performing the functions described herein, including, without limitation, a convertible laptop computer, a mobile computer, a laptop computer, a tablet computer, a smartphone, a notebook computer, a wearable computing device, a multiprocessor system, a mobile internet device, a telephony device, a consumer electronic device, and/or other portable computing device.

As discussed above, the convertible mobile compute device 100 is adjustable or configurable into one of several different physical configuration modes. For example, the convertible mobile compute device 100 is shown in several illustrative physical configuration modes in FIGS. 2-5. It should be appreciated, however, that some embodiments of the convertible mobile compute device 100 may contain fewer or more physical configuration modes, or alternative modes, than those illustrated herein.

Referring to FIG. 2, in some embodiments, the convertible mobile compute device 100 may be adjusted or configured into a closed mode 200. As shown, when in the closed mode 200, a user-facing side 304 of the lid 104 (see FIG. 3) abuts or confronts a user-facing side of the base 102 (see FIG. 3). Typically, when the convertible mobile compute device 100 is in the closed mode 200, the convertible mobile compute device 100 is in standby, powered off, or being operated by a user via an external device (not shown), such as a docking station, for example.

Referring now to FIG. 3, in some embodiments, the convertible mobile compute device 100 may also be adjusted or configured into a clamshell mode 300. As shown, when in the clamshell mode 300, the convertible mobile compute device 100 is opened such that the user-facing side 304 of the lid 104 is rotated away from the user-facing side 302 of the base 102 to allow a user to view each user-facing sides 302, 304 of the convertible mobile compute device 100. In the illustrative embodiment of FIG. 3, the lid-to-base angle 180 defined between the lid 104 and the base 102 is about 90 degrees. However, the convertible mobile compute device 100 may be considered to be configured in the clamshell mode when the lid-to-base angle 180 is greater than a minimum threshold (e.g., greater than zero degrees) and equal to or less than a maximum threshold (e.g., 180 degrees). Of course, in other embodiments, the particular range of lid-to-base angles that define the clamshell mode 300 may vary based on various criteria, such as the design or intended use of the convertible mobile compute device 100.

Referring now to FIG. 4, in some embodiments, the convertible mobile compute device 100 may also be adjusted or configured into a tent mode 400. It should be noted that the convertible mobile compute device 100 has been rotated generally 180° about a vertical axis between FIG. 3 and FIG. 4 to provide clarity of the tent mode 400 embodiment (i.e., the user-facing side 304 of the lid 104 is facing the user). It should further be appreciated that the display 112 may invert when the convertible mobile compute device 100 is placed in the tent mode 400 to provide proper viewing to a user. As shown in FIG. 4, in the tent mode 400, the lid 104 of the convertible mobile compute device 100 has been rotated from the base 102 even further relative to the clamshell mode 300 and generally resembles a tent from a side profile. In the illustrative embodiment of FIG. 4, the lid-to-base angle 180 defined between the lid 104 and the base 102 is about 270 degrees. However, the convertible mobile compute device 100 may be considered to be configured in the tent mode when the lid-to-base angle 180 is greater than a minimum threshold (e.g., greater than 180 degrees) and equal to or less than a maximum threshold (e.g., 360 degrees as shown by angle reference 402). Of course, in other embodiments, the particular range of lid-to-base angles that defines the tent mode 400 may vary based on various criteria, such as the design or intended use of the convertible mobile compute device 100. Additionally, it should be appreciated that the maximum threshold angle of the lid-to-base angle 180 that defines the tent mode 400 may be dependent upon the thickness of the lid 104 and/or base 102 of the convertible mobile compute device 100.

Referring now to FIG. 5, in some embodiments, the convertible mobile compute device 100 may also be adjusted or configured into a tablet mode 500. As shown, in the tablet mode 500, the lid 104 of the convertible mobile compute device 100 has been rotated relative to the base 102 such that the lid 104 abuts or confronts the base 102. As such, the convertible mobile compute device 100 generally resembles a tablet computer while in the tablet mode 500. In the illustrative embodiment of FIG. 5, the lid-to-base angle 180 defined by the lid axis 220 and the base axis 222 is about 360 degrees. However, the convertible mobile compute device 100 may be considered to be configured in the tablet mode 500 when the lid-to-base angle 180 is greater than a minimum threshold (e.g., greater than 300 degrees). Of course, the particular minimum lid-to-base angle that defines the tablet mode 500 may be different in other embodiments based on various criteria, such as the design or intended use of the convertible mobile compute device 100. Additionally, it should be appreciated that the minimum threshold angle of the lid-to-base angle 180 that defines the tablet mode 500 may be dependent upon the thickness of the lid 104 and/or base 102 of the convertible mobile compute device 100.

Referring now to FIGS. 6 and 7, the illustrative hinge assembly 106 includes a housing 600 from which a lid shaft 612 and a base shaft 614 protrude outwardly on either side of the housing 600 (although only one side is shown in each of FIGS. 6 and 7). A lid hinge bracket 602 is received on the lid shaft 612, and a base hinge bracket 604 is received on the base shaft 614. The lid hinge bracket 602 includes a lid mounting plate 620 and a mounting shaft tube 622. The lid mounting plate 620 is configured to be secured to the lid 104 of the convertible mobile compute device 100 and may include corresponding features, such as apertures, to facilitate such attachment. Similarly, the lid 104 may include a corresponding mounting plate (not shown) configured to mate or couple with the lid mounting plate 620 to secure the hinge assembly 106 to the lid 104. The mounting shaft tube 622 is configured to receive the lid shaft 612 when the lid hinge bracket 602 is coupled to the housing 600 as shown in FIGS. 6 and 7. When so coupled, the lid hinge bracket 602 is configured to rotate about a lid hinge axis 812, defined by the lid shaft 612.

Similar to the lid hinge bracket 602, the base hinge bracket 604 includes a base mounting plate 630 and a mounting shaft tube 632. The base mounting plate 630 is configured to be secured to the base 102 of the convertible mobile compute device 100 and may include corresponding features, such as apertures, to facilitate such attachment. Similarly, the base 106 may include a corresponding mounting plate (not shown) configured to mate or couple with the base mounting plate 630 to secure the hinge assembly 106 to the base 106. The mounting shaft tube 632 is configured to receive the base shaft 642 when the base hinge bracket 604 is coupled to the housing 600 as shown in FIGS. 6 and 7. When so coupled, the base hinge bracket 604 is configured to rotate about a base hinge axis 814, defined by the base shaft 614.

The hinge assembly 600 may include other components, such as those commonly found in a hinge assembly of a mobile compute device (e.g., a laptop). For example, the hinge assembly 106 may include various gears, bushings, and other mechanical devices, such as spur gears and friction bushings, to provide a suitable operational and holding torque such that the lid 104 is capable of maintaining its position relative to the base 102. Additionally, as discussed above, it should be appreciated that the illustrative hinge assembly 106 includes a lid shaft 612, a base shaft 614, a lid hinge bracket 602, and a base hinge bracket 604 on both ends of the housing 600 (i.e., on the left and right sides of the housing 600 as viewed from the position of the operator of the convertible mobile compute device 100.

Referring now to FIGS. 8 and 9, in the illustrative embodiment, the lid shaft 612 and, as such, the lid hinge axis 812 is offset from a lid centerline axis 822 of the lid 102. Similarly, the base shaft 614 and, as such, the base hinge axis 814 is offset from a base centerline axis 824 of the base 104. The lid centerline axis 822 is defined by the lid 102 and extends longitudinally through the center of the lid 102 along a direction from a front-side 862 to a rear-side 864 of the lid 102. Similarly, the base centerline axis 824 is defined by the base 104 and extends longitudinally through the center of the base 104 along a direction from a front-side 872 to a rear-side 8674 of the lid 102.

As shown in FIG. 8, the lid hinge axis 812 is offset vertically from the lid centerline axis 822 by a distance 830, and the base hinge axis 814 is offset vertically from the bae centerline axis 814 by a distance of 832. Each of the axes 812, 814 are offset relative to the corresponding centerline axes 822, 824 in a direction away from each other when the convertible mobile compute device 100 is positioned in the closed mode as shown in FIG. 8. That is, the lid hinge axis 812 is offset from the lid centerline axis 822 in a direction away from the base 104 and the base hinge axis 814 is offset from the base centerline axis 824 in a direction away from the top 102 when the convertible mobile compute device 100 is positioned in the closed mode. Conversely, the axes 812, 814 are offset relative to the corresponding centerline axes 822, 824 in a direction toward each other when the convertible mobile compute device 100 is positioned in the tablet mode as shown in FIG. 9. That is, the lid hinge axis 812 is offset from the lid centerline axis 822 in a direction toward from the base 104 and the base hinge axis 814 is offset from the base centerline axis 824 in a direction toward from the top 102 when the convertible mobile compute device 100 is positioned in the tablet mode.

Illustratively, the distances 830, 832 of offset of the axes 812, 814 from the centerline axes 822, 824 is equal. For example, in the illustrative embodiment, the lid hinge axis 812 is offset from the lid centerline axis 822 by about 0.075 millimeters, and the base hinge axis 814 is offset form the base centerline axis 824 by about 0.075 millimeters. Of course, in other embodiments, offset distances 830, 832 may be of a different value depending on various criteria such as the design and/or thickness of the lid 102 and/or base 104. Additionally, in some embodiments, the axes 812, 814 may be offset from the corresponding centerline axes 822, 824 by different distances.

It should be appreciated that because the lid hinge axis 812 is offset from the lid centerline axis 822 and the base hinge axis 814 is offset from the base centerline axis 824, the lid-to-base gap or distance 840 between the lid 102 and base 104 when the convertible mobile compute device 100 is positioned in the closed mode (FIG. 8) is smaller than the gap or distance 840 between the lid 102 and base 104 when the convertible mobile compute device 100 is positioned in the tablet mode (FIG. 9). For example, in the illustrative embodiment, the lid-to-base gap 840 is about 0.5 millimeters when the convertible mobile compute device 100 is positioned in the closed mode (FIG. 8) and about 0.8 millimeters when the convertible mobile compute device 100 is positioned in the tablet mode (FIG. 9). As such, by offsetting the hinge axes 812, 814, the lid-to-base gap 840 can be reduced when in the closed mode, which reduces the overall thickness of the convertible mobile compute device 100 when in the closed mode. In particular, because the hinge axes 812, 814 are farther from each other than the centerline axes 822, 824, the lid-to-base gap 840 is reduced when in the closed mode of FIG. 8

However, to ensure proper thermal performance of the convertible mobile compute device 100 a minimum base gap (i.e., a distance between the bottom of the base and any opposing structure) should be maintained. That base gap is typically defined by the feet 850 of the base 106. For example, when the convertible mobile compute device 100 is in set on a table, the feet 850 ensure a proper base gap between the table surface and the base 106 for proper thermal dissipation. As such, the lid-to-base gap 840 must be at least as large as the height of the feet 850 when in the tablet mode as shown in FIG. 9. As discussed in more detail below, such a requirement restricts or limits the lid-to-base gap, in any physical configuration mode, to the height of the feet 850. However, in the illustrative convertible mobile compute device 100, the offset of the hinge axes 812, 814 from the corresponding centerline axes 822, 824 allows for an increased lid-to-base gap 840 when the convertible mobile compute device 100 is positioned in the tablet mode (FIG. 9) relative to the closed mode (FIG. 8).

Conversely, as shown in FIGS. 10 and 11, the lid-to-base gap 1040 of a typical convertible mobile compute device 1000 is the same or otherwise equal when the typical convertible mobile compute device 1000 is positioned in either the closed mode (FIG. 10) or the tablet mode (FIG. 11). This is due because the lid hinge axis 1012 defined by the lid shaft 1042 of the hinge assembly 1006 of the typical convertible mobile compute device 1000 is located on the lid centerline axis 1022 defined by the lid 1002 of the typical convertible mobile compute device 1000. Similarly, the base hinge axis 1014 defined by the base shaft 1042 of the hinge assembly 1006 of the typical convertible mobile compute device 1000 is located on the base centerline axis 1024 defined by the base 1004 of the typical convertible mobile compute device 1000. That is, the hinge axes 1012, 1014 are not offset relative to the corresponding centerline axes 1022, 1024. Because the hinge axes 1012, 1014 are not offset relative to the corresponding centerline axes 1022, 1024, the lid-to-base gap 1040 is the same in both the closed mode and the tablet mode. Additionally, because a minimum base gap must be maintained and that base gap is defined by the feet 1050 of the typical convertible mobile compute device 1000, the height of the feet 1050 define the distance of the lid-to-base gap 1040, even when the typical convertible mobile compute device 1000 is positioned in the closed mode as shown in FIG. 10. As such, because the hinge axes 1012, 1014 are not offset relative to the corresponding centerline axes 1022, 1024, the overall thickness of the typical convertible mobile compute device 1000 is increased relative to the illustrative designs disclosed herein.

As shown in FIG. 12, the convertible mobile compute device 100 illustratively includes a compute engine 1202, an input/output (I/O) subsystem 1208, a data storage 1210, a communication subsystem 1212, peripheral device(s) 1214, display circuitry 1216, and the display 112. Illustratively, the compute engine 1202, the input/output (I/O) subsystem 1208, the data storage 1210, the communication subsystem 1212, and the optional peripheral device(s) 1214 are located in the base 102, while the display circuitry 1216 and display 112 are located in the lid 104. Of course, in other embodiments, various components of the convertible mobile compute device 100 may be located in the lid 104 or base 102. Additionally, in some embodiments, several of the foregoing components may be incorporated on a motherboard of the convertible mobile compute device 100, while other components may be communicatively coupled to the motherboard via, for example, a peripheral port. Furthermore, it should be appreciated that the convertible mobile compute device 100 may include other and/or additional components, such as those commonly found in a computer and/or computing device in other embodiments. Additionally, in some embodiments, one or more of the illustrative components may be incorporated in, or otherwise form a portion of, another component. For example, the memory 108, or portions thereof, may be incorporated in the processor 104 in some embodiments.

The compute engine 1202 may be embodied as any type of device or collection of devices capable of performing the various compute functions as described herein. In some embodiments, the compute engine 1202 may be embodied as a single device such as an integrated circuit, an embedded system, a field-programmable-array (FPGA), a system-on-a-chip (SOC), an application specific integrated circuit (ASIC), reconfigurable hardware or hardware circuitry, or other specialized hardware to facilitate performance of the functions described herein. Additionally, in some embodiments, the compute engine 1202 may include, or may be embodied as, one or more processors 1204 (i.e., one or more central processing units (CPUs)) and memory 1206.

The processor(s) 1204 may be embodied as any type of processor(s) capable of performing the functions described herein. For example, the processor(s) 1204 may be embodied as one or more single-core processors, multi-core processors, digital signal processors (DSPs), microcontrollers, or other processor(s) or processing/controlling circuit(s). In some embodiments, the processor(s) 1204 may be embodied as, include, or otherwise be coupled to an FPGA, an ASIC, reconfigurable hardware or hardware circuitry, or other specialized hardware to facilitate performance of the functions described herein.

The memory 1206 may be embodied as any type of volatile or non-volatile memory or data storage capable of performing the functions described herein. It should be appreciated that the memory 1206 may include main memory (i.e., a primary memory) and/or cache memory (i.e., memory that can be accessed more quickly than the main memory). Volatile memory may be a storage medium that requires power to maintain the state of data stored by the medium. Non-limiting examples of volatile memory may include various types of random access memory (RAM), such as dynamic random access memory (DRAM) or static random access memory (SRAM).

The compute engine 1202 is communicatively coupled to other components of the convertible mobile compute device 100 via the I/O subsystem 1208, which may be embodied as circuitry and/or components to facilitate input/output operations with the processor 1204, the memory 1206, and other components of the convertible mobile compute device 100. For example, the I/O subsystem 1208 may be embodied as, or otherwise include, memory controller hubs, input/output control hubs, integrated sensor hubs, firmware devices, communication links (e.g., point-to-point links, bus links, wires, cables, light guides, printed circuit board traces, etc.), and/or other components and subsystems to facilitate the input/output operations. In some embodiments, the I/O subsystem 1208 may form a portion of a SoC and be incorporated, along with one or more of the processor 1204, the memory 1206, and other components of the convertible mobile compute device 100, on a single integrated circuit chip.

The data storage 1210 may be embodied as any type of storage device(s) configured for short-term or long-term storage of data, such as, for example, memory devices and circuits, memory cards, hard disk drives, solid-state drives, or other data storage devices. Each data storage device 1210 may include a system partition that stores data and firmware code for the data storage device 1210. Each data storage device 1210 may also include an operating system partition that stores data files and executables for an operating system.

The communication circuitry 1212 may be embodied as any communication circuit, device, or collection thereof, capable of enabling communications between the convertible mobile compute device 100 and other computing devices, as well as any network communication enabling devices, such as an access point, network switch/router, etc., to allow communication over a corresponding network. Accordingly, the communication circuitry 1212 may be configured to use any one or more communication technologies (e.g., wireless or wired communication technologies) and associated protocols (e.g., Ethernet, Bluetooth®, Wi-Fi®, WiMAX, LTE, 5G, etc.) to effect such communication.

The peripheral devices 1214 of the convertible mobile compute device 100 may include any number of peripheral or interface devices. For example, the peripheral devices 1214 may include a display, a keyboard, a mouse, one or more data storage devices such as an internal or external hard drive, and/or other peripheral devices. The particular devices included in the peripheral devices 1214 may depend upon, for example, the intended use of the convertible mobile compute device 100. The peripheral devices 1214 are communicatively coupled to the I/O subsystem 1208 via a number of signal paths thereby allowing the I/O subsystem 1208 and/or processor 1204 to receive inputs from and send outputs to the peripheral devices 1214.

The display circuitry 1216 may be embodied as any type of circuitry and/or electronic devices for powering the display 112 and managing the display of information on the display 112. The display circuitry 1216 may be embodied as, for example, a graphical processing unit (GPU), video card, or other circuitry capable of controlling the display 112 to display information thereon.

As discussed above, the display 112 of the convertible mobile compute device 100 may be embodied as any type of display capable of displaying digital information such as a liquid crystal display (LCD), a light emitting diode (LED), a plasma display, a cathode ray tube (CRT), or other type of display device. In some embodiments, the display 112 may include, or otherwise be coupled to, a touchscreen 1218 to allow the user to interact with the convertible mobile compute device 100 by touching the display 112 in lieu of, or in addition to, the keyboard 110 or a peripheral device 1214 (e.g., a mouse).
